DETAILED DESCRIPTION

The examples set forth below represent the information to enableindividuals to practice the examples and illustrate the best mode ofpracticing the examples. Upon reading the following description in lightof the accompanying drawing figures, individuals will understand theconcepts of the disclosure and will recognize applications of theseconcepts not particularly addressed herein. It should be understood thatthese concepts and applications fall within the scope of the disclosureand the accompanying claims.

Any flowcharts discussed herein are necessarily discussed in somesequence for purposes of illustration, but unless otherwise explicitlyindicated, the examples are not limited to any particular sequence ofsteps. As used herein and in the claims, the articles “a” and “an” inreference to an element refers to “one or more” of the element unlessotherwise explicitly specified.

The term “persistent bi-directional communication channel” refers to acommunication channel between two computing devices, each of which mayunilaterally transfer data to the other via the communication channel,and which remains open after transfers of data until one of thecomputing devices explicitly closes the communication channel. TheWebSocket protocol, defined by Internet Engineering Task Force (IETF)Request for Comments 6455, is one example of a persistent bi-directionalcommunication channel. This may be contrasted, for example, withHypertext Transfer Protocol (HTTP), which is a uni-directional protocolwhere one computing device establishes a Transmission Control Protocol(TCP) connection and initiates a request, the other computing deviceprovides a response, and the TCP connection is automatically closed.

The phrase “cloud computing system” refers to a system that providesautomated on-demand self-service to multiple external entities via anapplication programming interface (API) over a network to a shared poolof configurable computing devices used to implement requests from theexternal entities for computing resources, such as data storage,application execution, and database management computing resources.

Iteratively polling a cloud computing system to obtain information fromthe cloud computing system requires the repeated setting up and tearingdown of connections, which increases processor and memory utilization.Moreover, iteratively polling a cloud computing system results inreceiving information slower than real-time due to the inter-poll delayassociated with polling. In many situations, the real-time receipt ofinformation regarding a computing resource implemented in a cloudcomputing system may be desirable such that corrective action, ifnecessary, can be conducted immediately.

The examples implement persistent real-time communication channelsbetween a computing device and a plurality of different cloud computingsystems. Among other advantages, the examples eliminate a need toiteratively poll and establish connections between the computing deviceand the cloud computing systems, facilitate the real-time receipt ofstatus and other information from the cloud computing systems, and allowthe real-time communication of actions to the cloud computing systems.

FIG. 1 is a block diagram of an environment 10 in which examples may bepracticed. The environment 10 includes a computing device 12 thatincludes a processor device 14, a memory 16 and a communicationinterface 18. The computing device 12 may be associated with an entity19, such as a business, that utilizes a plurality of different cloudcomputing systems 20-1-20-N (generally, cloud computing system 20). Asdiscussed above, each cloud computing system 20 comprises a system thatprovides on-demand access to one or more external entities, such as theentity 19 via the computing device 12, via a corresponding API 22-1-22-Nto a shared pool of configurable computing devices (CD) 24 used toimplement on-demand computing resources (CR) 26, such as data storage,application execution, and database management, at the request of thecomputing device 12 via a respective API 22. Although not illustrated,each cloud computing system 20 may provide such on-demand computingresources to any number of different entities. Non-limiting examples ofcloud computing systems 20 include Amazon® Web Services, Microsoft®Azure, and IBM® Cloud Services.

The computing device 12, in one example, provides a cloud managementfunction for the entity 19. The computing device 12 interacts with thecloud computing systems 20 via one or more networks 28. One mechanismfor interacting with the cloud computing systems 20 is via acorresponding API 22 that allows the computing device 12 to unilaterallyand on-demand request additional computing resources, such as additionaldata storage, additional application instances, and/or additionaldatabase management capabilities from one or more of the cloud computingsystems 20.

In one example, the computing device 12 also initiates a plurality ofpersistent bi-directional communication channels 30-1-30-N with theplurality of cloud computing systems 20. In one example, the persistentbi-directional communication channels 30 comprise WebSocketcommunication channels. Over time, the computing device 12 receivesreal-time messages from at least some of the cloud computing systems 20that identify a status 32-1-32-N of computing resources 26 implementedby the cloud computing systems 20.

FIG. 2 is a flowchart of a method for implementing persistentbi-directional communication channels 30 with cloud computing systems20, according to one example. FIG. 2 will be discussed in conjunctionwith FIG. 1. Initially, the computing device 12 initiates the pluralityof persistent bi-directional communication channels 30 with thecorresponding plurality of cloud computing systems 20, each cloudcomputing system 20 being operated by a different cloud provider andcomprising a plurality of computing devices 24 used to implementon-demand computing resources 26 on one or more of the plurality ofcomputing devices 24 at the request of different entities via an API 22(FIG. 2, block 100).

The computing device 12 receives, over a period of time, real-timemessages from at least some of the cloud computing systems 20 via thecorresponding persistent bi-directional communication channel 30 thatidentifies a status 32 of a computing resource 26 implemented in therespective cloud computing system 20 (FIG. 2, block 102).

By way of non-limiting example, a status 32 may include a processorutilization of a computing device 24 on which the computing resource 26is implemented, information identifying a failure and termination of acomputing resource 26, information indicating that a computing resource26 has been deployed and is available for use, information indicatingthat a computing resource 26 has been terminated and is no longeravailable for use, or information identifying a usage of a computingresource 26.

In addition, the computing device 12 may send, to one of the cloudcomputing systems 20 via the corresponding persistent bi-directionalcommunication channel 30, one or more commands relating to the computingresources 26. By way of non-limiting example, the computing device 12may send a command to deploy an application, a command to terminate anapplication, a command to provision a new virtual machine, or a commandto decommission a virtual machine. In some instances, the command may besent by the computing device 12 in response to the receipt of areal-time message from a cloud computing system 20 via a correspondingpersistent bi-directional communication channel 30. For example, inresponse to a real-time message from the cloud computing system 20-1that a computing resource 26 is handling a particular number ofconnections, the computing device 12 may issue a command to instantiateadditional computing resources 26.

The persistent bi-directional communication channels 30, among otherfeatures, allow real-time instantaneous communications from thecomputing device 12 to a cloud computing system 20, and from a cloudcomputing system 20 to the computing device 12, without a need toestablish new connections for each such communication, and without theprocessing overhead associated therewith.

FIG. 3 is a block diagram of a display device 34 of the computing device12 on which a user interface 36 is presented that provides informationregarding computing resources 26 based on real-time messages receivedvia the persistent bi-directional communication channels 30 according toone example. A status portion 38-1 includes status information 40regarding a computing resource 26 that comprises an application instanceimplemented in the cloud computing system 20-1. The status portion 38-1also includes status information 42 regarding a computing resource 26that comprises disk space implemented in the cloud computing system20-1. A status portion 38-2 includes status information 44 and statusinformation 46 regarding computing resources 26 that comprise twoapplication instances implemented in the cloud computing system 20-2. Astatus portion 38-3 includes status information 48 and statusinformation 50 regarding computing resources 26 that comprise twoapplication instances implemented in the cloud computing system 20-N.

A basic input/output system (BIOS)58 may be stored in the non-volatile memory 54 and can include the basicroutines that help to transfer information between elements within thecomputing device 12. The volatile memory 56 may also include ahigh-speed RAM, such as static RAM, for caching data.

The computing device 12 may further include or be coupled to anon-transitory computer-readable storage medium such as a storage device60, which may comprise, for example, an internal or external hard diskdrive (HDD) (e.g., enhanced integrated drive electronics (EIDE) orserial advanced technology attachment (SATA)), HDD (e.g., EIDE or SATA)for storage, flash memory, or the like. The storage device 60, and otherdrives associated with computer-readable media and computer-usablemedia, may provide non-volatile storage of data, data structures,computer-executable instructions, and the like.
